The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
Selective pressures created by environmental factors can lead to success of <span>mutual individuals. So it is D</span>
The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.
- Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
- The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
- Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
- Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.
Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte

<span>The gradual thickening of the uterine lining also called Endometrial Hyperplasia is often caused by having excess estrogen without enough progesterone to balance it. During menstruation, the estrogen causes the lining to thicken in preparation for pregnancy. When the progesterone is made during the second half of the cycle and the progesterone levels drop, the lining is shed. And if the ovulation didn’t occur, progesterone is not made and the lining is not shed properly, the lining will keep on building gradually that may lead to cancer in some women. </span>
